Abstract Details

2017, Master of Science, Ohio State University, Electrical and Computer Engineering.
Two-dimensional (2D) materials have attracted much attention in the last decade. The discovery of graphene has shown that such single-atom-layer sheets exfoliated from crystalline are fundamentally different from their parent materials. Since almost all atoms are exposed to the surface, the covalent surface termination can be used as a powerful tool to tune materials properties. Via the topotactic deintercalation of CaGe2 with HCl and CH3I, methyl-terminated Germanane (GeH) and hydrogen-terminated Germanane (GeCH3) are synthesized. As two promising candidates to future optoelectronic and sensing applications, the physical and chemical properties of GeH and GeCH3 need to be explored. The result presented here used a complement of atomic force microscopy (AFM), Kelvin probe force microscopy (KPFM), surface photovoltage spectroscopy (SPS), cathodoluminescence spectroscopy (CLS) and photoluminescence (PL) to characterize the band gap and defect states in hydrogen and methyl-terminated germanane. The results can provide guidance to fabricate them and control defects in them.
